Abstract
O presente trabalho foi realizado nas fazendas NUPEARIDO e Lameirão, localizadas nos municÃpios de Patos (PB) e Santa Terezinha (PB), respectivamente, no perÃodo de fevereiro a agosto/2000, com o objetivo de verificar a influência de adubos orgânicos (esterco de bovino, caprino, asinino e composto orgânico) e intervalos de corte (três e seis meses após o plantio) na composição bromatológica da moringa (Moringa oleifera Lam). O plantio foi realizado em covas de 0,30m x 0,30m x 0,30m, com plântulas de 15 cm de altura, aproveitando-se o perÃodo chuvoso, distantes 1,5m entre elas. As plantas foram cortadas aos três e seis meses após o transplantio. Avaliou-se a rebrota do primeiro e do segundo corte analisando-se a percentagem de MS (Matéria Seca), FDN (Fibra em Detergente Neutro), FDA (Fibra em Detergente Ãcido), PB (ProteÃna Bruta) Cinzas e HC (Hemicelulose). Verificou-se que a adubação orgânica realizada com estercos bovino e caprino afetou o teor de HC aos seis meses e o corte aos três meses afetou os teores de FDN, FDA, PB e Cinzas, exceto o teor de MS e HC do caule. A rebrota da moringa apresentou maiores teores de PB e Cinzas do que plantas não cortadas. Palavras-chave: semi-árido; forragem; análise bromatológica. ABSTRACT The present work was carried out in two UFPB Experimental Stations (NUPEARIDO (Luvissolo Planossólico (Bruno não Cálcico) and Lameirão farms (Luvissolo) located in the semi-arid region of Brazil), from February to August/2000. Its objective consisted to verify the influence of organic fertilizers (bovine, goat and donkey manures, and organic compost of plants remains) and cut intervals (three and six months after seedling planting) in the bromatological composition of moringa (Moringa oleifera Lam) above ground forage. Planting of 15cm high seedlings took place in February, into 0.30m x 0.30m x 0.30m openings in the soil, arranged in a 1.5m x 1.5m grid, in the beginning of the rainy season. Plants were cut three and six months after planting. Also, new stems were cut three months after the first cutting. Collected materials were analyzed for Dry Matter (DM), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Crude Protein (CP), ash and Hemicellulose (HC) contents. Forage from six-month-old plants showed an increased HC content when fertilized with bovine or goat manure. Forage from three-month old plants showed different NDF, ADF, PB, and ash contents than the older ones, except for stem DM and HC. Three-month-old moringa sprouts showed higher CP and ash contents than material from three or six month old non-cut plants. Keywords: semi arid area; forage; bromatological composition.</div
